REFERENCE ELECTRODE CLEANING

• Drain the old filling solution, rinse with an adequate HI 7072 solution, drain, then refill with HI 7072 solution.
• Do not use an electrode if crystalized salts are visible inside the electrode. Drain electrode, dissasamble

and rinse internal body with deionized water. Reassemble and refill with fresh fill solution.

• The internal chamber of this electrode is gell filled. If the electrode has been left dry for long periods of

time the gell may be dehydrated and stable measurements may not be obtenable. Dissasamble
electrode and soak internal assembly in HI 7072 filling solution. Verify the ceramic is wetted by the fill
solution. Warming the solution slightly (50 °C) before soaking will hasten this process. Permit the
electrode to cool completely while immersed in this solution.
